24 Claims. (Cl. 178-25) This invention pertains to printing telegraph apparatus and more particularly to improvements in tabulating mechanisms therefor.

It is the principal object of this invention to provide in a recording device a simple, eflicient, and reliable tabulating mechanism which is selectively responsive to code combinations of signalling impulses for controlling tabulation recording.

A feature of the invention is the provision of means for automatically rendering the recording device ineffective in response to recording operations under predetermined conditions.

Another feature of the invention resides in the provision of a lock-out means, effective when the movable type carriage of the recorder has reached its end-of-line position, to prevent the selective operation of the tabulating device.

A further feature consists in a single lock-out means, effective when the movable carriage has reached its end-of-line position, to prevent simultaneously the performance of the tabulating,

printing, and spacing functions of the recording apparatus.

The above and other objects of the present invention are accomplished by the provision in a printing telegraph apparatus of a tabulator bar which extends acro:s the front of the machine and is pivotally carried by brackets mounted in the typing unit and capable of swinging toward and away from the type carriage. The tabulator bar carries a number of adjustable stop members which determine the positions at which the type carriage comes to rest after spacing during the tabulating cycle. The spacing mechanism of the printing apparatus comprises a three-toothed ratchet adapted to cooperate with a pair of pawls which are actuated by the printing bail to function as an escapement mechanism so that, upon each revolution of the main shaft, the spacing worm gear associated with the spacing ratchet is permitted to rotate one-third of a revolution.

A series of function levers is provided which operate selectively in accordance with the setting of a series of selector vanes. Among this series of function levers is a tabulating function lever which,,when selected, is drawn forward into the selector vanes under spring tension. When this occurs, the rear extension of the function lever raises and thereby lifts the rear end of a horizontal member. When the rear end of this horizrntal lever is raised, it lifts, through suit-able linkage, the upper space pawl out of engagement with the tooth of the spacing ratchet, at which time the front end of said horizontal member is lowered thereby unlatching the tabulating bar to permit the latter to be biased by its spring toward the type carriage. When the upper space pawl is thus disengaged, the lower space pawl remains in its normal position entirely free of the teeth on the escapement ratchet, thus permitting the spacing worm gear to make one complete revolution instead of only one-third of a revolution during the time that the main shaft rotates through one revolution, and therefore the carriage will be'spaced continuously at a speed whi h is three times that of normal spacing speed. To bring the carriage to rest after tabulating it is necessary to permit the upper space pawl to drop again into engagement with a tooth on the spacing ratchet. This latter function is efiected by the coaction of a cam element assembled to the carriage and one of the adjustable members carried by the tabulator bar. This cam forces or cams the tabulator bar forward or away from the carriage, against spring tension, and in doing so permits said horizontal member to be restored to its normal position into latching engagement with the tabulator bar. This restoration action of the horizontal member permits the upper space pawl again to fall into engagement with a tooth on the spacing worm ratchet, which thereupon brings the carriage to rest.

The present invention also comprises a further latching means for preventing the initiation of the tabulation operation after the movable type carriage has reached the end of a line, as well as means for simultaneously looking out automatically the printing and spacing functions. These features are accomplished by the provision of an adjust-able member on the tabulator bar similar to that previously alluded to except that it is provided with an enlarged cam portion which acts to swing the tabulator bar outwardly or away from the type carriage a greater extent 40 than normally, thus rendering the lock-out means efiective.

For a complete understanding of details not disclosed herein which form no part of the present invention, reference may be had to U. 8. Patent No, 1,904,164, issued April 18, 1933, to S. Morton et al. Reference may also be had to copending application Serial No. 735,094 filed July 14, 1934, between which and the present application there is community of subject matter.

Briefly, having reference to Figs. 1, 3, and 6, a printing apparatus to which the tabulating mechanism of the present invention is applied comprises a typing unit (shown generally in section in Fig. 3) which includes a primary selecting mechanism indicated generally as, N (Fig. 6) which is of the sword-and-T type disclosed in U. S. Patent No. 1,745,633 to S. Morton et a1. (fully disclosed in the first mentioned patent), and a secondary selector or selector vane assembly indicated generally as I2. The selector vane assembly I2 controls through a series of bell cranks I3 (Fig. 1) a corresponding series of curved code bars I4 carried in a movable type carriage. As set forth in the first mentioned patent, this type carriage, indicated generally as I5, is movable longitudinally in respect to a stationary platen indicated generally as I3 (Fig. 3). The type carriage I5 also carries a ribbon feed mechanism indicated generally as I1.

Referring particularly to Fig. 6, a motor I3 supplies power through gear I9 to a main operating shaft; 2| which carries the spacing mechanism indicated generally as 22 and the selector cam assembly indicated generally as 23. As is known in this type of device, power is communicated from the motor to the driven shaft through a grab clutch such as 25. Portion 24 of grab clutch 25 constantly rotates with the shaft 2|, which has also frictionally connected thereto the spacing mechanism 22 and the selecting cam drum 23. Portion 24 is cooperatively engaged with the driven portion 26 when throw-out lever 21 is operated in timed relation with the reception of code signals.

The spacing mechanism 22, which will be described more in detail hereinafter, controls through gear 28, shaft 29, gear3l, and rack 32 (Fig. 3), the movement of type carriage I5 to form character spaces, tending in this movement to wind up the carriage return spring mechanism indicated generally as 33. Upon receipt of the carriage return signal, function bar 34 is actuated selectively in the manner described in Patent No. 1,904,164 so as to permit spring 35 to rotate lever 36 suddenly against stop 31 to raise, through bell crank 33, portion 33 of grab clutch 4|. Carriage return mechanism 33 is thereupon permitted, due to the energy stored up therein, to return the carriage I5 to its normal or beginning-of-line position.

Positioned in operative relation with and parallel to the main operating shaft 2| is an auxiliary shaft 42 on which are carried various mechanisms, for example, printing bail 43, function bail 43 and the escapement mechanism for g the spacing mechanism 22. The printing bail 43, which is actuated by a printing spring (not shown) in proper timed relation in the operative cycle, functions to reciprocate a pull bar operating member 44 to cause the operation of a 10 type bar, as clearly described in the aforementioned patent.

The selector vanes as set forth in Patent No. 1,904,164 control a series of function levers among which and provided especially for accomplishing 15 the objects of the present invention are a tabulating function lever 45 (Fig. 'l) and a lock-out function lever I33 (Fig. 3), which like the other function levers'described in said patent are pivoted on a common pivot rod 43 and are assemso bled in a slot in the function lever comb 41. These function levers 45 and I33, like the rest of the function levers of the series, are provided with individual springs 43 and I34, respectively. tensioned between each and the printer frame as which tend to rotate the respective function levers 45 or I33 about pivot 46 but, as clearly set forth in Patent No. 1,904,164, are restrained by the function lever ball 46 acting through rod 56 on arm I36. 30

Before describing further the function of lever 45, a detailed description of the spacing mechanism will be given. Having reference to Figs. 3 and 5 there is shown mounted on the main shaft 2| and located centrally of the apparatus a sleeve 35 member 5| which comprises escapement ratchet 52 and escapement worm 53 which are operably connected thereto. Sleeve member 5| is operably connected to the hub of a disc 54 by means of interengaging tongue and groove members 55. 40 Collar 56 is pinned to main shaft 2| and is ro-. tatable therewith. Interposed between disc 54 and collar 56 is disc 51 of frictional material; for example, felt. By means of a helical compression spring 53, sleeve 5| is frictionally connected to 45 shaft 2| through the friction clutch comprising members 54, 53, and 51. Sleeve 5| is thereby rotatable with main shaft 2| unless arrested by the escapement pawls of the spacing mechanism 22 as will presently appear. 50

Referring to Fig. 3 it will be noted that ratchet 52 is provided with three teeth or notches 6|, Gin, and 6"), the escapement of which will allow the type carriage I5 to be moved forward one step or character space for each actuation of the 55,

printing ball 43. As indicated, the escapement mechanism comprises levers 62 and 33, pivotally mounted on bail shaft 42, and lever 64 adjustably fixed toprinting ball 43. Spring 65 normally tends to rotate levers 62 and 63 in opposite di- 60 rections, since it is common to both levers. Lever 62 is normally urged by spring 65 in a counter clockwise direction so that laterally disposed end 66 engages tooth 6| of ratchet 52, thus arresting the rotation of said ratchet. Lever 63 is normally 55 held out of engagement with ratchet 52 against the tension of spring 65 by the action of lever 64 against laterally disposed end 61.

Lever 34 is pivotally connected to printing ban 43 at 63 and is provided at 63 with a-siot and screw adjusting means, whereby the correct relative position of escapement levers 62 and 63 with respect to ratchet 52 may be determined. The

spacing operation occurs immediately following 75 or subsequent to the printing of a character in the following manner.

Upon the printing of a character, lever 64 is caused to rotate slightly in a clockwise direction with printing ball 43 which moves clockwise about bail shaft 42, thereby transferring this motion to lever 82 through its laterally disposed end tripping its end 66 out of engagement with tooth 6| and permitting ratchet 52 to rotate slightly in a clockwise direction under the influence of friction clutch members 54 to 51 (Fig. 5) until arrested by the engagement of tooth 8|a with laterally disposed end I2 of lever 63 which lever was free to rotate in a clockwise direction under the tension of spring into the path of oncoming tooth 6|a. Ratchet 52 is thus restrained from rotation by lever 63 until the completion of the printing of a character at which time printing bail 43 and associated lever 84 are caused to rotate in the opposite direction by the action of a printing cam (not shown). Restraint of lever 82 by lever 84 through end II is thereby removed, permitting lever 82 to rotate in a counterclockwise direction under the influence of spring 65 into the path of tooth Nb of ratchet 52. During this counterclockwise movement of lever 64, and immediately after the aforementioned release of lever 52, lever 83 is caused to rotate in a like direction due to the action of lever 64 on end 81 thereof, thereby disengaging end 12 of lever 63 from tooth Bla and allowing ratchet 52 to continue its rotation until arrested by the engagement of end 88 of lever 82 with tooth 8|b.

It is obvious that since worm 53 and ratchet 52 are integrally connected to sleeve 5|, said worm 53 will have normally the same intermittent or step-by-step motion as was hereinbefore seen to be imparted to ratchet 52. Worm 53 is meshed with worm gear 28 (Figs. 3 and 6) which is loosely mounted on vertical shaft 29, and is operably connected thereto by means of jaw clutch 4|. Worm 53 and gear 88 are so related that onethird revolution of worm 53 will rotate gear 28 through a distance which, through gear 3| and rack 32 causes the type carriage to be stepped forward one character space.

From the foregoing it will be observed that character spacing takes place automatically with the printing of each character; that is, the spacing function is merged into the printing operation. It is well known that there is a code combination allotted to each type bar, but it is possible, however, to employ a code combination, commonly known as the spacing signs, which is identified with no type bar but which will nevertheless initiate the printing operation. Therefore, the spacing between words is accomplished in exactly the same manner as set forth when a spacing signal is received, except that no type 1 bar is operated and consequently no character is printed.

In accordance with the present invention, continuous spacing may be effected upon the receipt of a code combination known as the tabulating code combination which functions to initiate the operation of the tabulating mechanism.

The mechanically operated tabulating arrangement of the present invention comprises a tabulator bar 8| extending across the front of the printing apparatus, as shown in Fig. 1, which is provided with depending portions 82 and 83 through which bar 8| is pivotally mounted on bracket 84 carried in the printer frame. Thus tabulator bar 8| is adapted to be swingable toward or away from the type carriage |5. Bar 8| is also provided with a longitudinal slot 85 extending substantially the entire length of the bar. Into this slot are adjustably movable stop members 86 which are adapted to be clamped to the bar 8| by means of screws 81 and clamps 88 individual to each stop member 86 (Fig. 3). As indicated in Fig. 6, these stop members 88 are each provided with an inclined or cam portion 89, specially conformed so as to provide quick action upon cooperation with a cam element I carried by the type carriage, to terminate suddenly the tabulating operation.

Tabulator bar 8| is also provided, intermediate the depending portions 82 and 83 (Fig. 1) and suitably positioned relative to function lever 45, with another depending portion 9|. Attached to and depending from portion 9| is a bar 92 the lower end of which is provided with an aperture 93 having its upper left-hand comer (as viewed in Fig. '7) conformed so as to provide a reentrant 20 stepped portion 94. The tabulator bar 8|, as indicated in Fig. 6, normally tends to move toward the printing apparatus due to the action of a spring 95.

Cooperating with the stepped portion 94 (Fig. 7) is one arm 96 of a lever 91 pivotally carried at 98 on a support 99 secured to the function lever comb 41. The extremity of arm 96 is provided with a laterally disposed portion |0| (Fig. 4) which cooperates with portion 94 of member 92. At the end of arm |02 of lever 91 (Fig. 3) is rigidly carried a vertically extending member I03 the upper end of which is provided (in the present embodiment) with an open ended slot adapted to engage a pin |04 carried by escapement lever 82.

Function lever 45 is provided with a horizontal portion 605 (Figs. 3 and 7) so conformed that its extremity |06 engages the lower edge of arm I02 of lever 9'! such that when function lever 45 is permitted to rotate in a clockwise direction under the action of its spring 48 upon the proper setting of the vanes i0! in response to the tabulation code signal, the end E08 thereof is elevated, causing lever 91 to rotate slightly in a clockwise direction against the tension of its spring |08. The end |0| of arm 98 is thus moved downwardly clear of portion 94, thus permitting spring to urge the tabulator bar 8| inwardly (or toward the left as viewed in Fig. '7) until wail I09 of member 92 engages lug IN. The series of adjustable stops 88 are thus moved inwardly into the path of a cam member (Figs. 3 and 6) pivoted at 2 on a portion 3 integrally formed on a bar 5 which is comparable to bar 53 shown in Fig.

l of Patent No. 1,904,164 employed for retaining the bell crank levers |3 in operable relation to vanes |0'|. Thus cam I, like bar 5 and bell cranks I3, is movable with the type carriage l5 for character spacing. Cam I normally tends to rotate in a clockwise direction about pivot ||2 due to the action of spring H8, but its clockwise rotation is limited by the coaction of a stop pin 1, carried thereon, with the end of bar 5. Thus upon the rightward movement of type carrlage l5 (Fig. 6) cam due to its non-rotatability in a clockwise direction, will, by its camming action on stop member 86, actuate tabulator bar 8| outwardly; but upon the leftward movement of type carriage |5, cam upon P the selection of function lever 4!, arm I32 and consequently portion I33 carried thereon will be raised and in so doing will, through pin I34. lift escapement lever 32 out of engagement with the teeth of the ratchet 32 which, since the lever 33 is prevented from engaging the teethof the ratchet 52 due to its being held in inoperative position by lever 34, permits the worm gear to make one complete revolution instead of onethird of a revolution during the time that the main shaft rotates through one revolution, and therefore the carriage will be spaced continuously at a speed which is three times that of normal spacing so long as the escapement lever 32 is held out of operative engagement with ratchet 32. which, as we have seen, is maintained in this position due to the engagement of lug IIII with the under side of step portion 34. Thus carriage It will be moved continuously until cam III coacts with one of the series of stops 33, when cam III will urge through stop 36 tabulator bar 3| outwardly, as viewed in Fig. 6 (or in a clockwise direction as viewed in Fig. 7), the effect of which is to disengage lug IIII from portion 34, whereupon lever 31 will again be rotated in a counterclockwise direction by its spring I 33 into the position shown in Fig. 7. in which event portion I33 (Fig. 3) carried on arm I02 of lever 31 will again be lowered, permitting escapement lever 32 under action of spring 33 to engage one of the teeth GI, 3Ia, or Bib of the ratchet 32.

The function lever 45, however, will have been returned to its non-selective position, as shown in Fig. 'l, at the completion of the first revolution or cycle of operation of the main shaft 2I because of the fact that during the cycle pursuant to the reception of the tabulating signal, the

function bail 43 will have been reciprocated once so that shaft 83, upon the down-stroke of bail 43, will permit spring 43 to urge lever 45 into cooperative relation with vanes I01 only so long as to effect the selection, and hence the resulting disengagement of pawl 62 whereafter shaft 50 upon its upward or return movement will cam the function lever 45 through arm I33 thereof vaway from the vanes II" where it will be held in Fig. '7 by a spring I23 so that stop pin I24 carried on latch I2I bears against the outer edge of arm 32 (also shown in Fig. 2).

To achieve the tabulation lock-out function there is also adjustably carried on the tabulator bar 3| adjustable member I25 which, as shown in Fig. 6, is larger than stops 33 and is provided with a higher cam portion I23 so that when the cam III carried on the movable carriage I5 coacts therewith, the tabulator bar 3| will be caused to rotate a much greater extent- As indicated, a dwell of substantial length is also provided on the inner edge of member I25 to prevent premature return of bar 8| to its inward position. This movement, as viewed in Fig. 7, will also cause depending arm 32 to swing leftwardly a greater is positioned beneath lug III of arm 33 of the tabulation lever 31: thus in this condition the reception of a tabulation code signal will have no effect since, even if function lever 45 should attempt to rotate under the action of its spring 43 in response to the tabulation signal, it will be restrained therefrom due to the impossibility of rotating, through its arm III, lever 31 in a clockwise direction because at this time latch I2I is in a position to prevent such rotation. Of course, upon the reception of the carriage return signal,

' themovable type carriage II will be returned to its beginning of line position and tabulator'bar 3| will again be permitted to swing inwardly as viewed in Fig. '7, under the action of its spring 35, thus retracting latch I2I from lug IIII.

The present invention also provides the feature of locking outautomatically the printing and spacing functions when the type carriage I5 has reached the end of the line. This feature is desirable in the event that the carriage return signal is lost or transformed in transit or by its losing or gaining an impulse, thereby changing the identity of the signal. Therefore, if a carriage return code signal is thus lost or transformed, the type carriage I5 will not be returned at the end of the line preparatory to beginning the next line, and the spacing and printing operation will continue to be performed, thus tending to urge the type carriage I5 beyond the limits of its movement and consequently causing damage to the mechanism.

To preclude this possibility the tabulator bar 3I, as shown in Figs. 1, 2, and 3, is provided with a second depending bar I23 adjacent the previously mentioned bar 32. Bar I23 has formed at its lower extremity a laterally disposed portion I23 which coacts with the specially formed end I3I of arm I32 of a special locking-out function lever I33 (Figs. 2 and 3). Lever I33 is devoid of code notches and is pivotally mounted on function lever shaft 43 and is adapted to be urged toward the selector vanes ill! by a spring I34 individual thereto. Thus when the type carriage II has reached its end-of-line position and has coacted with adjustable stop I25 to move tabulator bar 3| to a greater extent than normally. as previously described in connection with the tabulator lock-out function, the bar I 23 will be swung in a clockwise direction, as viewed in Fig. 3, so that its laterally disposed end I29 will be entirely clear of the are described by the end I35 of portion I3I of special function lever I33. In view of this movement of tabulator bar 3I and bar I23, special function lever I33 is free to move in a clockwise direction under the action of its spring I34 so that the upper extremity of arm I33 of the function lever I33 will be disposed beneath an upturned edge I31 (Figs. 2 and 3) formed on the function lever bail 40, as fully described in Patent No. 1,904,164.

Briefly, as described in said patent, the function lever bail 40 is provided with upturned edges I31 which are adapted to span certain of the function levers wherein it is desired to prevent printing or spacing operations, this being effected by permitting arms I33 of such function levers to intercept the upturned edges I3'I after only a limited movement thereof, suflicient to prevent the spacing and printing functions. Of course, as fully described hereinbefore, the shaft 33 of the function ball 40, due to its camming action on the inner surface of arm I33 invariably returns the function levers to their normal or inoperative position. Thus, so long as the type carriage I3 remains in its end-of-line position and holds tabulator bar 8| cammed outwardly so that lug I29 of lever I28 clears portion I35 of function lever I33, the printing and spacing operations will be prevented because of the'blocking relationship between upturned edge I31 of function lever bail 40 and the arm I36 of function lever I33. Upon return of the type carriage I5 to its beginning-ofline position, tabulator bar BI and bar I28 will assume their perpendicular position, portion I29 being thereby again disposed beneath inturned portion I35 of function lever I33. It is to be understood that lug I29 will clear portion I35 only when tabulator bar 8| has been actuated to the greaterextent by adjustable stop I25, and hence, when cam III coacts with stops 86, member I28 will not be moved sufliciently to disengage lug I29 from portion I35.
